PROFILE
David Mcdowall
Over a three-month period, this developer enhanced the ministryofjustice/hmpps-approved-premises-api repository by delivering three new backend features focused on external referral and application workflows. They implemented CRN-based referral endpoints for CAS1 and CAS2v2, enabling external consumers to retrieve referral data efficiently. Using Kotlin and the Spring Framework, they designed and exposed new REST APIs, introduced a dedicated data model for suitable CAS3 applications, and consolidated external application endpoints with a status prioritization system. Their work emphasized secure data exposure, clear commit traceability, and simplified integration for downstream consumers, resulting in improved data accessibility and streamlined decision-making processes.

Feb 1, 2026February 2026: Delivered the Unified External Applications API with Status Prioritization for ministryofjustice/hmpps-approved-premises-api. Consolidated and standardized external application endpoints to simplify integrations and introduced a priority system for application statuses to improve retrieval of suitable applications. This refactor reduces integration complexity, speeds up decision-making for external applications, and improves data consistency across downstream consumers. Implemented via two refactor commits with clear traceability: e5491acbc90483de79cd3300db6595e05de4f30e and 5eec0ca0803629ca1d72a433b54e6afc383df92f.

Jan 1, 2026January 2026 monthly summary for ministryofjustice/hmpps-approved-premises-api: Delivered CAS3: Retrieve Suitable Applications by CRN API endpoint to fetch suitable CAS3 applications by CRN, including a new data model for suitable applications and status-determination logic. This enables faster triage and improved decision traceability in CAS3 workflows. No major bugs fixed this period; stabilization tasks were completed for the new endpoint. Demonstrated strong API design, data modeling, and commit-based traceability that supports scalable maintenance and audits.

Nov 1, 2025November 2025: Delivered external referral access improvements for the HMPS Approved Premises API. Implemented two new CRN-based referral endpoints to support CAS1 and CAS2v2, enabling external consumers to retrieve referrals by CRN via SAS. This involved adding and wiring the new endpoints, with commits 913945d9bd4dfc3c9baa45259b30491ef329cecb and 5168b69beec2c12211ac7bd45be153f1bcb12070 respectively. Outcome: improved data accessibility for partner integrations, reduced manual data pull, and strengthened API coverage for external use cases. Skills demonstrated: REST API design and versioning, secure exposure of internal data, incremental feature delivery with clear traceability via commits, cross-version support (CAS1 and CAS2v2).
